Control Systems: What Are They? (Open-Loop & Closed-Loop Control System Examples)

What is a Control System? A control system is defined as a system of devices that manages, commands, directs, or regulates the behavior of other devices or systems to achieve a desired result. A control system achieves this through control loops, which are a process designed to maintain a process va

On Off Control Controller: What is it? (Working Principle)

What is an On Off Controller? Sometimes, the control element has only two positions either it is fully closed or fully open. This control element does not operate at any intermediate position, i.e. partly open or partly closed position. The control system made for controlling such elements is known

Control Engineering: What is it? (And its History)

What is Control Engineering Control system engineering is the branch of engineering which deals with the principles of control theory, to design a system which gives yields the desired behavior in a controlled manner. Hence, although control engineering is often taught within electrical engineering

Nyquist Stability Criterion: What is it? (Plus Matlab Examples)

What is Nyquist Stability Criterion? Nyquist stability criterion (or Nyquist criteria ) is defined as a graphical technique used in control engineering for determining the stability of a dynamical system. As Nyquist stability criteria only considers the Nyquist plot of open-loop control systems, it

SCADA System: What is it? (Supervisory Control and Data Acquisition)

What is SCADA? SCADA stands for “Supervisory Control and Data Acquisition.” SCADA is a process control system architecture that uses computers, networked data communications, and graphical Human Machine Interfaces (HMIs) to enable high-level process supervisory management and control. SCADA systems

Programmable Logic Controllers (PLCs): Basics, Types & Applications

What is a PLC? PLC stands for “Programmable Logic Controller.” A PLC is a computer specially designed to operate reliably in harsh industrial environments, such as extreme temperatures and wet, dry, and/or dusty conditions. PLCs are used to automate industrial processes such as a manufacturing plant

Steady State Error: What is it? (Steady-State Gain, Value & Formula)

What is Steady State Error? Steady-state error is defined as the difference between the desired value and the actual value of a system output in the limit as time goes to infinity (i.e. when the response of the control system has reached steady-state). Steady-state error is a property of the input/o

How to Find the DC Gain of a Transfer Function (Examples Included)

What is a Transfer Function? A transfer function describes the relationship between the output signal of a control system and the input signal. A block diagram is a visualization of the control system that uses blocks to represent the transfer function and arrows representing the different input and

Rise Time: What is it? (Equation And How To Calculate It)

What is Rise Time? Rise time is defined as the time taken for a signal to cross from a specified low value to a specified high value. In analog and digital electronics, the specified lower value and specified higher value are 10% and 90% of the final or steady-state value. So the rise time is typica
